lRAUL:-CHAIR.

Application filed February 15, 1917, Serial No. 148,866. Renewed June1S, 1918.

To all whom, t may concern.'

Be it known that I, AUGUST G. LIEBMANN, a citizen of the United States,residing at Chicago, in the county of Cook and State of llinois, haveinvented certain. new and useful Improvements in Rail-Chairs, of whichthe following` is a specification.

` rlhis invention relates to railway track appliances and moreparticularly to rail chairs.

rfhe object of the invention is to provide a rail chair particularlyadapted for use on soft wood ties or treated soft wood ties and whichwill permit of both vertical and lateral adjustment of the rails forsurface and gage without disturbing the primary fastening devices.

A further object is to provide a rail chair, the construction of whichis such as to render unnecessary the use of bolts extending through thetie and, consequently, obviate the corrosion of bolt heads on theunderside of the tie which often occurs in saline soils.

A further object is to provide the bed plate with an overhangingabutment adapted to receive a cap screw, the free end of which seats ina socket in the rail clamping member and serves to hold said member inengagement with the base flange of a rail.

A further object is to provide the bed plate of the chair with dependinghalf dowels which act as binders and also serve to prevent checks andAcracks in the tiek from expanding or widening as the tie seasons and,therefore, prevent splitting of the tie.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

Figure 1 is a perspective view of a rail chair embodying the presentinvention;

Fig. 2 4is a top plan view;

Fig. 3 is a transverse sectional view;

Fig. f1 is a bottom plan view with the tie removed.

Specification of Letters Patent.

Patented Sept. 24, 1918.

sei-iai No. 239,880.

Referring to the drawings, A represents a rail having a standard crosssection, and B a tie supporting the rail. Mounted upon the cross tie Bis a bed plate 5, preferably a malleable casting, although the plate maybe otherwise formed, if desired. The bed plate 5 is substantiallyrectangular in shape and pref rably extends the entire width of theupper surface of the tie, shown.

Depending from the bed plate 5 and preferably formed integral therewith,are depending half dowels or extensions G, one of said extensions beingpreferably arranged near each corner of the plate and all of said dowelshaving their open sides facing in the saine direction. The bed plate 5is permanently secured to the upper surface of the cross tie by means ofprimary fastening devices, in eferably in the forni of screw spikes 7arranged at diagonal corners of the bed late and which pass throughsuitable openings 8 formed in said bed plate, as shown. The half dowels6 not only assist in anchoring the bed plate on the cross tie but alsoact as binders and serve to prevent the checks and cracks in the tiefrom widening or expanding as the tie seasons and, therefore, preventpren'iature splitting of the tie. @paced inwardly from the opposite endsof the bed plate 5 are upstanding abutments 9, preferably formedintegral with the plate and extending approximately one-half the widththereof, these abutments being arranged at diagonally opposite cornersof the bed plate and being connected therewith by terminal webs 10 and11. The abutments 9 are further reinforced and strengthened by aplurality of buttressing webs 12 which eX- tend from the upper ends ofthe abutinents 9 `to the adjacent end of the plate, as shown.

Each abutment 9 is provided with an inwardly extending arm 13 whichoverhangs the bed plate 5 and is provided with a threaded opening 111adapted to receive a cap screw 15. The opening in the arm 13 issurrounded by a reinforcing collar 16, the upper" surface of which ispreferably flat, said reinforcing collar being connected with the upperend of the adjacent abutment 9 by a reinforcing rib 17 which forms ineffect a continuation of the central buttressing webb 12.

Arranged beneatlreach arm 13 is a rail clamping member 18, preferablyoctagonal in shape and provided with a depending ec- 2 of the drawings.

overhang'ing portions andV side portions, rail' centric portion 19Aadapted to bear against the adjacent longitiulinal edge of the baseflange of the rail. Each rail clamping meniber is also provided Witha-circumferential flange Z0 having its lovver face inclined and itsmarginal edge formed With a plurality of angular faces; 2l adapted tobear against the inner facesof the adjacent abutments 9 whereby to holdthe rail in different positions of lateral adjustment with respect tothe bed plate. Each clamping. member is also formed With a centrallydisposed socket 22 adapted to receive the tapered end of the adjacentcap screw 15 so that ivhen said cap screw' is tightened the clampingmember will be securely held in engagement With the base flange oftherail and-thus hold said rail from accidental displacement.

rlhe inner Webs 1l are preferably longer than the outer ivebs 10 and areof suiiicient height and length to form in effect side abutments forengagement with the rail clamping members`19, as best shown in Fig. Byloosening the cap screws l5 and rotating the clamping members 19, therail may be adjusted laterally on Jthe bed plate for gage, While byadjusting the cap screivs vertically and inserting a shim 23 beneath therail,-said rail may be adjusted vertically for surface, it of coursebeing understood that after adjustment `of the rail has been eected thecap screws will beY tightened so as to firmly hold the rail clampingmembers 19 in proper position. Owing to the fact that the dependingdovvelsV G' form auxiliary anchoring devices for the bed plate, the useof bolts extending entirely through thetie is rendered unnecessary and,consequently, corrosion of bolt heads on'V the underside of the tie,which oftenl occurs in saline'soils, is obviated; It will further benoted that certain of the half doivels 6 are so arranged as toaccommodate the threaded ends of the adjacent screw spikes 7 therebyserving to reinforce and strengthen the spikes and receive the lateralthrust thereon. This form ofA chair and fastening device is extremelysimple inl construction and can be manufactured at a minimum cost.
